description This poster is focused on the indirect measurement of the Higgs boson width through the constraints on the off-shell Higgs coupling in the high mass region using the H->4l decay channel. The production cross section for the off-shell Higgs boson with decay into vector bosons is proportional to the product of the couplings squared for production and decay. Unlike the on-shell cross section, this observable is independent of the total Higgs width. Therefore, the ratio of the on and off-shell couplings provides an indirect measurement on the total Higgs width. Two different versions of the posters (CONF note and paper results) are provided.
